This differs from a regular null-modem cable in that the target machine has DSR
looped to DTR, not to DCD. Note that this cable is directional.

unconnected. As well, PCs do not require a valid DSR line for operation. Thus,
a simpler cable can be constructed that is bi-directional:

PC ----- null-modem adapter ----- cable with pin 6 removed ------ target machine
